The socket connection state is indicated via the 'bool connected' field
in the SocketChardev struct. This variable is somewhat misleading
though, as it is only set to true once the connection has completed all
required handshakes (eg for TLS, telnet or websockets). IOW there is a
period of time in which the socket is connected, but the "connected"
flag is still false.
The socket chardev really has three states that it can be in,
disconnected, connecting and connected and those should be tracked
explicitly.

In qmp_chardev_open_socket the code for connecting client chardevs is
split across two conditionals far apart with some server chardev code in
the middle. Split up the method so that code for client connection setup
is separate from code for server connection setup.

The tcp_chr_wait_connected method can deal with either server or client
chardevs, but some callers only care about one of these possibilities.
The tcp_chr_wait_connected method will also need some refactoring to
reliably deal with its primary goal of allowing a device frontend to
wait for an established connection, which will interfere with other
callers.
Split it into two methods, one responsible for server initiated
connections, the other responsible for client initiated connections.
In doing this split the tcp_char_connect_async() method is renamed
to become consistent with naming of the new methods.

The TLS creds option is not valid with certain address types. The user
config was only checked for errors when parsing legacy QemuOpts, thus

Pull all code for validating options out into a new method
qmp_chardev_validate_socket, that is called from the main
qmp_chardev_open_socket method. This adds a missing check for rejecting

Add the ability for a caller to wait for completion of the
background thread to synchronously dispatch its result, without
needing to wait for the main loop to run the idle callback.
This method needs very careful usage to avoid a dangerous
race condition with the free'ing of the task. The completion
callback is normally invoked from an idle callback registered
with the main loop context. The qio_task_wait_thread method
must only be called if the completion callback has not yet
run. The only safe way to achieve this is to run the
qio_task_wait_thread method from the thread that executes
the main loop.
It is generally a bad idea to use this method since it will
block execution of the main loop, however, the design of
the character devices and its usage from vhostuser already
requires blocking execution.

When chardev is multiplexed (mux=on) there are a lot of cases where
CHR_EVENT_OPENED/CHR_EVENT_CLOSED events pairing (expected from
frontend side) is broken. There are either generation of multiple
repeated or extra CHR_EVENT_OPENED events, or CHR_EVENT_CLOSED just
isn't generated at all.
This is mostly because 'qemu_chr_fe_set_handlers()' function makes its
own (and often wrong) implicit decision on updated frontend state and
invokes 'fd_event' callback with 'CHR_EVENT_OPENED'. And even worse,
it doesn't do symmetric action in opposite direction, as someone may
expect (i.e. it doesn't invoke previously set 'fd_event' with
'CHR_EVENT_CLOSED'). Muxed chardev uses trick by calling this function
again to replace callback handlers with its own ones, but it doesn't
account for such side effect.
Fix that using extended version of this function with added argument
for disabling side effect and keep original function for compatibility
with lots of frontends already using this interface and being
"tolerant" to its side effects.
One more source of event duplication is just line of code in
char-mux.c, which does far more than comment above says (obvious fix).

IMHO it's because there's a race between the main thread and iothread
when stopping the thread in following sequence:
main thread iothread
=========== ==============
aio_poll()
iothread_get_g_main_context
set iothread->worker_context
iothread_stop
schedule iothread_stop_bh
execute iothread_stop_bh [1]
set iothread->running=false
(since main_loop==NULL so
skip to quit main loop.
Note: although main_loop is
NULL but worker_context is
not!)
atomic_read(&iothread->worker_context) [2]
create main_loop object
g_main_loop_run() [3]
pthread_join() [4]
We can see that when execute iothread_stop_bh() at [1] it's possible
that main_loop is still NULL because it's only created until the first
check of the worker_context later at [2]. Then the iothread will hang
in the main loop [3] and it'll starve the main thread too [4].
Here the simple solution should be that we check again the "running"
variable before check against worker_context.

Cast the kernel start address to the target bit length.
This ensures that we calculate the initrd offset to a valid address for
the architecture.
Steps to reproduce the original problem (reported by Alex):
Build U-Boot for the virt machine for riscv32. Then run it with
$ qemu-system-riscv32 -M virt -kernel u-boot -nographic -initrd <a file>
You can find the initrd address with
U-Boot# fdt addr $fdtcontroladdr
U-Boot# fdt ls /chosen
Then take a peek at that address:
U-Boot# md.b <addr>
and you will see that there is nothing there without this patch. The
reason is that the binary was loaded to a negative address.

Depending of the host hardware, copying and extracting VM images can
take up to few minutes. Add verbosity to avoid the user to worry about
VMs hanging.

The option -G of usermod command will remove user from other groups
not listed, i.e.: $USER will belong only to group 'docker' after
following the documentation as is.
From usermod(8) manual page:
If the user is currently a member of a group which is not listed,
the user will be removed from the group. This behaviour can be
changed via the -a option, which appends the user to the current
supplementary group list.
This patch improves the situation by adding the -a option to the
usermod command, which will just append user to the supplementary
group list.

A lot of architectures can run their 32 bit cousins on KVM so the
kvm_available function needs to be a little less restricting when
deciding if KVM is available.

Now the underlying basevm support passes these along we can expose
some additional variables to our Makefile to allow more customised
tweaking of the build. For example:
make vm-build-freebsd TARGET_LIST=aarch64-softmmu \
EXTRA_CONFIGURE_OPTS="--disable-tools --disable-docs" \
BUILD_TARGET=check-softfloat

This allows us to invoke the build with a custom target (for the VMs
that use the {target} format string specifier). Currently OpenBSD is
still hardwired due to problems running check.

The "make check" target calls check-qtest which has the appropriate
system binaries as dependencies so we shouldn't need to do two steps
of make invocation. Doing it in two steps was a hangover from when our
make check couldn't run tests in parallel.

It's easier to move around the images then, by replacing the
subdirectory with a symlink. Allows to share the images between
multiple qemu checkouts for example.

My editor keeps putting squiggly lines under a bunch of the python
lines to remind me how non-PEP8 compliant it is. Clean that up so it's
easier to spot new errors.

If we have a persistent mapping we don't need the QEMU binary copied
into the container as the kernel has already opened the file and will
pass the fd in. However the support libraries will still need to be
there.

binfmt_misc configured with the "F" flag opens the interpreter at
config time. This means it can use an already open file-descriptor to
run QEMU so there is no point trying to copy the binary into a
container.

When copying a QEMU binary into a linux-user docker image we should
check what the current configured binfmt_misc path is rather than
just assuming "/usr/bin/qemu-bin". Obviously if the user changes the
configuration afterwards they will break their images again.
